Question

X2+2k(x-2)+5=0 find values (not value) of k

Answer 1

Answer:

x=-5-4k/2+2k

Step-by-step explanation:

firstly open the brackets which will be

1. x2+2kx-4k+5=0
2. arrange the equation;
3. x2+2kx=-5-4k
4. factorise it so that u get x
5. x(2+2k)=-5-4k
6. divide both sides by 2+2k to get x
7. x(2+2k)/2+2k=-5-4k/2+2k
8. so the 2+2k/2+2k will get canceled and you will remain with x
9. thats why the answer is x=-5-4k/2+2k
